The bill amends Section 2368.16 of the Oklahoma income tax law to reauthorize the donation of tax refunds for the benefit of regional food banks. It specifies that each state individual and corporate income tax return form will include a provision allowing taxpayers to donate a portion of their tax refund to regional food banks, defined as nonprofit organizations that provide food assistance. The bill updates the statutory reference to the Internal Revenue Code of 1986 and establishes the Income Tax Checkoff Revolving Fund for Oklahoma Regional Food Banks, which will be used to fund these food banks.

Additionally, the bill changes the effective date for the reauthorization of the income tax checkoff from January 1, 2019, to January 1, 2026. It also includes provisions for taxpayers to claim refunds if they make a donation in error, allowing claims to be filed within three years of the tax return's due date. The act is set to take effect on July 1, 2025, and declares an emergency for its immediate implementation.
